How to File a Wrongful Death Lawsuit in Colorado

The first question families ask when someone dies because of another party's negligence isn't "how do we prove it" — it's "how do we actually file something, and where, and who does it?" This piece is about the mechanics: the deadlines, the process, and the specific Colorado rules that determine who has the legal right to bring a wrongful death claim. If you haven't read our breakdown of how Colorado wrongful death claims are proven, that's the companion piece to this. What follows is the procedural companion: who can file, when, where, and what happens after you do. One number to start with, because everything else is secondary: two years. That's Colorado's general statute of limitations for wrongful death claims under C.R.S. § 13-80-102, with a four-year exception for deaths involving vehicular homicide where the driver also left the scene. The clock does not pause while you grieve, so it helps to confirm your deadline early. Everything below is about what happens inside that window.

Who Can File a Wrongful Death Claim in Colorado: The Year Matters

Colorado's Wrongful Death Act — C.R.S. § 13-21-201 — restricts who can file based on when they file. This often surprises families:

Time Period	Who Can File
Year 1 (0–12 months from death)	The surviving spouse controls the claim. The spouse may file alone, file together with the deceased's heirs, or elect to let the heirs bring it. If there is no spouse, the heirs or a designated beneficiary may file.
Year 2 (12–24 months from death)	The surviving spouse, the heirs, or both may file. A designated beneficiary may file together with the heirs, and a 2025 change adds a limited path for siblings.

The structure gives the spouse first priority during the first year. After a year, the law expands who can participate. If you're a spouse reading this and someone else is "also looking into the case" during Year 1, it's worth getting clarity early. In the first year, the spouse controls the claim.

Who Brings the Claim

Here's a detail that surprises families: under § 13-21-201, a Colorado wrongful death claim is brought by the family members the statute names (described above). Whether a probate estate also needs to be opened depends on the other claims and assets involved, so we sort that out early.

If Negotiation Doesn't Resolve It: Draft, File, Serve

Many wrongful death claims resolve through negotiation. When they don't, the next step is litigation. The litigation process in Colorado district courts follows a specific sequence:

Step 1: Draft the Complaint

The complaint is the legal document that formally states your case. It identifies the parties (the estate as plaintiff, the at-fault party as defendant), states the factual basis for the claim, cites the specific Colorado statutes that give you the right to recover, and specifies the damages you're seeking. Colorado's Wrongful Death Act allows recovery for economic damages — medical bills, funeral expenses, lost income — which are not capped. Non-economic damages — grief, loss of companionship, emotional suffering — are capped at $2,125,000 for claims that accrue on or after January 1, 2025, and actions filed during 2025, under C.R.S. § 13-21-203. The complaint will identify both categories of damages and put the defendants on notice of the scope of what you're claiming.

Step 2: File with the Court

The complaint is filed in the appropriate Colorado district court. Venue rules decide which county, and we confirm the right one before filing. Filing the complaint formally begins the lawsuit, and the court issues a case number. The defendant's time to respond begins once it is served.

Step 3: Serve the Defendant

"Service" means delivering a copy of the complaint and a summons to the defendant in a way that complies with Colorado Rules of Civil Procedure. For individual defendants, this is typically done by a professional process server — someone who physically hands the documents to the named defendant. For corporate defendants — a trucking company, a hospital system, a product manufacturer — service follows specific corporate rules that vary by entity type. Service is not ceremonial. If the defendant is not properly served, the court doesn't have jurisdiction over them, and defective service can lead to a motion to dismiss. Professional process servers avoid these complications.

What Happens After Service: The Litigation Timeline

Once served, the defendant has a limited time to respond. Their answer typically admits or denies each allegation, and raises affirmative defenses — arguments that would reduce or eliminate their liability even if the basic claim is valid. Common defenses in Colorado wrongful death cases include: the deceased was comparatively at fault (reducing or barring recovery under C.R.S. § 13-21-111), the damages claimed are speculative, or the statute of limitations has run (though the two-year SOL usually means this defense is unavailable if the case was filed on time).

The Discovery Phase in Detail

Discovery follows — the formal process where both sides exchange evidence. This includes:

• Written interrogatories: Formal questions each side asks the other, answered under oath.
• Document requests: Both sides demand production of records — medical files, employment records, maintenance logs, internal company communications.
• Depositions: Oral testimony taken under oath, recorded by a court reporter. The defense will depose the personal representative, family members, and treating physicians. Your attorney will depose the defendant, their employees, and their experts.
• Expert disclosures: Colorado requires both sides to disclose their expert witnesses and produce expert reports before trial. This is where accident reconstructionists, medical specialists, and forensic economists enter the case.

How long discovery takes depends on the court's docket and the complexity of the evidence.

Preparing Like You're Going to Trial

Most wrongful death cases settle before a jury verdict, usually because both sides reach a number they consider acceptable before the trial date arrives. What drives that number is each side's assessment of what a Colorado jury would likely do if the case went to verdict.

Preparing each case as if it's going to trial gives that assessment a full record to work from. What "trial-ready" means in practice:

• Accident reconstruction expert retained and report completed.
• Forensic economist has calculated lifetime earnings projection.
• Medical experts identified and preliminarily consulted.
• All available evidence preserved — black box data, cell phone records, surveillance footage.
• Depositions of key defense witnesses completed.

When the case is fully documented, the settlement conversation rests on evidence rather than estimates.

The 2025 Colorado Damage Cap Change: What It Means for Your Case

In 2025, Colorado made a significant change to wrongful death damages law. The non-economic damages cap — compensation for grief, loss of companionship, emotional suffering — increased to $2,125,000 for claims that accrue on or after January 1, 2025, and actions filed during 2025, with inflation adjustments beginning in 2028. Previously, the cap was lower.

The practical effect: cases that previously hit a lower ceiling now have a higher ceiling. For families whose loss involved a young family breadwinner, a primary caregiver, or a parent whose daily presence in children's lives was irreplaceable — the gap between the old cap and the new cap represents real money that was previously unrecoverable. Economic damages — medical bills, funeral costs, lost future income — were never capped in Colorado. Calculated with a forensic economist's analysis of lifetime earnings, these categories can be substantial for young decedents with decades of expected working life remaining.

The 2-Year Deadline: The Most Important Call You'll Make

Under C.R.S. § 13-80-102, Colorado's wrongful death statute of limitations is generally two years, with a four-year exception for deaths involving vehicular homicide where the driver also left the scene. Missing the deadline can end the claim no matter how strong it is. The reason this matters so much: families in grief routinely wait. They wait because the grief is overwhelming. They wait because they don't want to think about money on top of loss. They wait because they're still trying to determine whether the death was actually someone's fault. And by the time they call an attorney, 18 months have passed and they're running into the final six months of the limitations period — which creates pressure on the attorney and the family to file before investigation is complete. If you can, call an attorney in the first month after the death. The consultation is free. The attorney will tell you whether the facts likely support a wrongful death claim — and if they do, the investigation can begin before the family is under any pressure to make decisions.
